What Is Soil Stabilization and Why Is It Important?


Soil stabilization is a process that allows you to improve the quality and stability of your soil. Soil stabilization techniques can be divided into two categories: mechanical and non-traditional. Each of these types of stabilizers has its own set of benefits and uses. 

Chemical Stabilization

Soil stabilization is an important engineering technique to increase soil stiffness and improve its bearing capacity. It is often used on-site development projects and roadways. Chemical stabilization is adding chemicals to the soil to improve its physical properties.

The effects of a chemical stabilizer are most visible in soils with low fine content. This is because the additive will be more effective when interacting with less soil.

One of the most common chemical soil stabilization processes is using lime. Lime helps improve the workability of soil and decreases its plasticity. In addition, it helps with water repulsion.

Other additives include silanes and enzymes. Silanes improve the compaction density of poor soils. Enzymes can solve problems such as swelling.

Mechanical Stabilization

Soil stabilization is an important component of any construction project. It can help to reduce the risk of collapse, improve engineering properties, and prevent water penetration. These benefits are achieved through chemical, physical, or biological methods.

Mechanical stabilization of soil refers to a process whereby two or more types of soil are mixed and compacted. This process changes the structure, gradation, and porosity of the material. In the early 1980s, it became a popular method of stabilizing the earth for construction projects. However, this method is costly and time-consuming.

A soil stabilization Houston can be used to build foundations for a house, a parking lot, or an airfield. It is also often applied to existing road and pavement surfaces to increase their strength and stability.

Enzymatic Stabilization

Enzymatic soil stabilization is an important tool for improving the properties of the soil. The use of enzymes may be more cost-effective than other methods. It is also more environmentally friendly. Bio enzymes are organic catalysts that speed up chemical reactions in the soil.

Bio enzymes have been used in the field of stabilization for some time now. They are derived from plant matter, bacteria, or fungi. Their chemistry has yet to develop fully, but they are effective in several applications.

Bio enzymes work by reducing the soil’s affinity to water. This reduces the likelihood of soil cracking. They also reduce the need for conventional energy-intensive stabilizers. Since enzymes are not toxic, they are not harmful to the environment. In addition, they can save money on transportation.

Non-Traditional Stabilizers

Soil stabilization involves altering soil properties, whether mechanically, chemically, or biochemically. These methods are applied to different types of soil. The effects of soil stabilizers on different soils can vary, so it is important to perform tests to determine the effectiveness of a product.

Traditional chemical stabilizers include lime, cement, and fly ash. They are typically sold in concentrated liquid form. But non-traditional chemical stabilizers are often cheaper and may provide alternative options for stabilizing sulfate-rich soils.

Stabilizers of soil are typically categorized into two types: chemical and polymer. Chemical stabilizers are often purchased as concentrated liquids, while polymers are typically marketed as soap powders. Each type requires a unique application process.

Chemical stabilizers typically use a long-repeating molecule to bond with the soil particle. This enables the soil to retain its shape when wet. When the molecule dissolves, it weakens the bond.

Common Uses

Soil stabilization is an important process for development projects, parking lots, roadways, and other applications where a stable base is needed. The process improves the engineering properties of soils, reducing the risk of collapse and saving money.

Stabilizing agents are chemicals that seal the space between soil particles. These chemicals also make the soil more compact and prevent water penetration. Some of the common stabilizing agents include calcium chloride, portland cement, sodium silicate, and lime.

Cement is the oldest stabilizer. It is available in solid form or as cement in emulsions. However, it can be expensive. An alternative is to use bitumen, which can also be used as cement. But bitumen could be more environmentally friendly.

Fly ash is another common soil stabilizer. It is a byproduct of coal-fired power plants. This product can be used as a bonding agent and react chemically with a sodium-based solution.
